GRATE FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 228,266, dated June 1, 1880,

Application filed March 4, 1880.

To all whom it may concern;

Be it known that I, JONATHAN MOORE, Jr., of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Grates for Stoves, Ranges, and Furnaces, of which the following is a specification.

Grates have heretofore been made in which one or more of the bars are movable, so as to agitate the fire and shake out the ashes. The clinkers, however, are liable to become wedged in between the bars. In other instances the entire grate has been movable; but the fire rests upon the same, and there is nothing to press up the fuel and allow the ashes to descend.

My present invention is made for lifting up the particles of fuel from the grate and allow ing the ashes to fall, thereby stirring the fire and shaking down the ashes without disturbing the grate-surface itself. This is accomplished by means of fingers that are oscillated and caused to pass up between the gratebars to lift up the carbonaceous materials and allow the ashes to shake down through the bars, and when not in use the stirring-fingers are sufficien tly below the grate notto be burned or injured by the heat and not to obstruct the draft or the fall of the ashes.

In the drawings, Figure l is a crosssection of the grate, and Fig. 2 is a side view of the stirring-fingers with the grate in section.

The grate is of any desired size and shape. The cross-bars a and longitudinal bars 1) are united or cast in one, as usual, and in grates for ranges and stoves that are made to dump there will be trunnions c at the ends of the grate a b, and on these the entire grate can be revolved when the contents of the fire-chamber are to be discharged.

The dotted line at 2 2 illustrates the direction in which the grate is tipped.

Upon the under side of the grate there are journal boxes or bearings d, for the axial bar 0 of the stirrer, and this bar 6 has transverse projecting arms 5 i, that come beneath the openings between the grate-bars a a, and upon these arms 1' there are upwardly-projecting fingers 0 0.

(N0 model.)

A handle or rattler, l, is connected with the axial bar 6, preferably by means of a loop, a, forming a mortise between itself and the bar 0, into which the end of the rattler lis passed, and by it the bar 6 is moved and the arms and fingers are oscillated, so that the fingers pass up between the grate-bars a sufficient distance, first at one side and then at the other, to stir the fire, press up the pieces of carbonaceous matter, and shake down the ashes, thus clearing the fire and also saving the coal.

The normal position of the arms and fingers is represented by full lines in Fig. 1, and the dotted lines show the same when oscillated to one side. The extent of movement of. the arms and fingers may be limited by stops.

The shaking-arms and axial bar turn with the grates when the fuel is to be dumped, and they are not in the way of the necessary movement.

I am aware that agitators in the form of fingers have been thrust up through between the bars and then moved horizontally; also, that agitating-plates have been rocked upon the same axis as the dumping-grate; and, also, that fingers upon levers have been operated by a shaker to pass up between the bars.

In my grate the fingers are upon arms that are supported by a shaft pivoted to the grate itself, and oscillate up through between the grate-bars, and the dumping-grate swings or pivots parallel to but above the axis of the agitators.

I claim as my invention The combination, with a dumping-grate, of bearings projecting downwardly from such grate, an axial bar, transverse projecting arms having fingers oscillating upon the axial bar, that is parallel, or nearly so, with the pivots upon which the grate tips, but below such pivots, substantially as set forth.

Signed by me this 1st day of March, A. D. 1880.
